Water accumulated in exhaust pipe of Mercedes-Benz e300l

Treatment method of water inlet of Mercedes-Benz e240 engine: 1. If the engine is only mixed with water vapor from the air filter, we can clean the water vapor from the air filter, throttle and cylinder with simple treatment. 2. If there is more water in the engine but it does not affect normal driving, but the sound is loud, it may be that there is a small amount of water in engine oil and gasoline. We need to change the oil and clean the engine related accessories; 3. If there is a lot of water, it means that the engine has been flooded, but the car engine has not started and caused no damage. We need to drain the water, clean it up, then reinstall it and change the oil. 4. If the engine can't run after starting because of too much water, and the cylinder, connecting rod and piston of the engine have been deformed, then it can be concluded that the engine has been scrapped, and we can only replace it with a new engine or directly scrap the car.
